BBQ and hush puppies...sounds like you could use a good green to round that out. I like to serve greens beans (cooked with some bacon of course and topped with lots of butter) when I make hush puppies. Puppies will soak up the that buttery liquid just right!

Most restaurants serve butter or a pseudo-butter spread alongside. Some restaurants down east (that's eastern NC) will serve the basket of hushpuppies with honey butter. The Spouse always sprinkles his with Texas Pete. I like my mine nekkid, hot out of the fryer.

I think we're going to get into regional differences here. In NC and Tidewater VA a basket of puppies is served immediately upon being seated in every BBQ restaurant around. They're not a side dish, per se. They come with every meal automatically, just like some places might put down a bread basket. Of course, fried fish restaurants will also serve hushpuppies with all their fried meals.

Green tomato relish sounds pretty good on catfish but I've never seen it served in a restaurant, let alone with hushpuppies.
